Segregation-Assisted Plasticity in Ni-Based Superalloys [PDF]
Metallurgical and Materials Transactions A, 2018 Abstract Correlative high-resolution transmission electron microscopy and energy-dispersive X-ray spectroscopy are used to study deformation-induced planar faults in the single-crystal superalloy MD2 crept at 800 °C and 650 MPa. Segregation of Cr and Co at microtwins, anti-phase boundaries (APB), and complex/superlattice extrinsic and ...

Slip analysis in a Ni-base superalloy [PDF]
Acta Materialia, 2005 A Ni-base superalloy single crystal with Gamma/Gamma' structure was tested at room temperature along the , and directions. Consistent with previously reported investigations, this alloy did not obey the Schmid law and the CRSS (critical resolved shear stress) was noticeably lower for the -oriented samples.

Probing single crystal orientation by X-ray diffraction for nickel-based superalloys
Results in Physics, 2021 The deviation angles of Ni-based single crystal superalloys are investigated by two techniques of rotating orientation X-ray diffraction (RO-XRD) and back-reflection Laue X-ray diffraction (BRL-XRD).

Ni–W diffusion barrier: Its influence on the oxidation behaviour of a β-(Ni,Pt)Al coated fourth generation nickel-base superalloy [PDF]
, 2009 A Ni–W base diffusion barrier (DB) has been developed to limit interdiffusion between a fourth generation Ni-base superalloy (MCNG) and a Pt-modified nickel aluminide bondcoat. After long term oxidation, the DB layer permits to reduce the Al depletion in

Cohesive Strength and Structural Stability of the Ni-Based Superalloys [PDF]
Materials, 2021 The influence of alloying elements on the cohesive strength of metal heat-resistant alloys (HRAs) is analyzed. Special parameters are introduced to characterize the individual contribution of each alloying element. These are the partial molar cohesion energy of the matrix (χ) and the cohesive strength of the grain boundaries (η) and can be calculated ...

Beneficial Effect of Pt and of Pre-Oxidation on the Oxidation Behaviour of an NiCoCrAlYTa Bond-Coating for Thermal Barrier Coating Systems [PDF]
, 2011 The oxidation behaviour of a thermal barrier coating (TBC) system is a major concern as the growth of the thermally grown oxide (TGO) layer on the bondcoating creates stresses that greatly favour the thermal barrier spallation.
